To all whom 'it may concern:

Be it known that I, WILLIAM C. HARTi MANN, e citizen of the United States of Amer-` ica., residn at Lansing, in the county of Ingham on State of Michi an, heveinvented certain new und useful m rovements in CreamfSepm-ators, of which t e following is a. specification, reference being had therein to the accompanying drawings.

This' invention vrelates to a centrifugal cream` separator bowl, and especially to certain V errangen'lents of the lining increesin the efficiency of the action, and the ease wit which it may be cleaned Without disturbing the adjustment.

VThe invention consists in the matters hereinaftersetv forth, Vand more particularly pontedout inthe ap ended clalms.

In- 'the drawings, igure 1 is n view .in longitudinal section of a cream separator bowl and liner embodying features of the invention. Fig.2 is a. view in section on line l 1-1 of Iig."Y 3 is a. view in detail of a. distributing pipel` ciallyto Figs. 1 und 2, a. central tubular stem Y l which constitntesthe ullmilk inlet` duct, 'terminates inn Het base' 2 within-rim 3, the Stein itself beingtiered form ii conica-1 4.'
